Abstract (en)

[origin: EP3104195A1] A method and apparatus are provided for tracking a binary offset carrier (BOC) navigation signal in a receiver by locating the main correlation peak of the BOC signal, wherein the BOC autocorrelation function is composed of a main peak, corresponding to zero offset, and multiple side peaks, each of known width. The method comprises performing a first set of correlations to determine a coarse location of the main peak, wherein the first set of correlations is used to discriminate the main peak from the side peaks; and performing a second set of correlations to determine a fine location of the main peak, wherein the second set of correlations is performed within said known width. The second set of correlations can be defined as a subset of the first set of correlations. The coarse location of the main peak from the first set of correlations is used to constrain or correct the fine location from the second set of correlations such that the fine location is determined for said main peak to perform said tracking.
